    Study Notes

    Temperature Change

    • The graph shows an isothermal temperature change, meaning the temperature remains constant.

    Volume Change

    • The volume of the perfect gas is inversely proportional to the pressure. This means that as pressure increases, volume decreases, and vice versa.

    P and P'

    • 'P' represents the initial pressure of the perfect gas.
    • 'P' represents the final pressure of the perfect gas.

    Nature of the Process

    • The process is reversible and adiabatic.
      • Reversible means the process can be reversed without any loss of energy.
      • Adiabatic means no heat exchange occurs between the system and its surroundings.

    Relationship between 'n' and Specific Heat Capacities

    • The provided information does not mention 'n' or specific heat capacities. Therefore, no conclusions can be drawn about their relationship.
